June 28, 2011 (Padre Dam) -- Padre Dam Municipal Water District’s Mountain Top Reservoir Retrofit Project recently received the 2010 Project of the Year Award from the San Diego & Imperial County chapter of the American Public Works Association (APWA) and the 2010 Award of Merit in Water Treatment by the San Diego Section of the American Society of Civil Engineers (ASCE).
In 2010, Padre Dam engineers completed a $2.5 million upgrade to the Mountain Top Reservoir. The project, successfully replaced the deteriorating wooden roof with a new innovative aluminum roof, improved the overflow structure and seismically and structurally upgraded the existing concrete reservoir. The improvements allow the reservoir to maintain regulatory compliance, improve local water reliability and quality, extend its service life for several decades, and reduce greenhouse gas emissions.
A key component of Padre Dam’s water reliability is the ability to safely store water for future use. The 2.4 million-gallon Mountain Top Reservoir provides reliable water supply storage of potable water for the Crest and La Cresta Heights communities.
The award winning aspect of the renovation is the minimal cost and minimal impact to the surrounding neighbors that was ultimately accomplished. AECOM engineering was retained during the project to provide alternative evaluations, design and bidding/construction support. Opting to retrofit instead of demolishing and re-building saved the District approximately $500,000 and reduced construction related impacts. The new aluminum roof resists corrosion, offers strength and durability and requires less maintenance. Trips to the site will be reduced as a result of the aluminum roof, making it cost-effective and less harmful to the environment. Customer impact was also minimized through the use of a temporary water storage tank to maintain service levels and operations while the reservoir was off-line.
APWA, the American Public Works Association, provides professional development, advocacy and networking opportunity within the public works field. The San Diego Imperial Counties Chapter annually recognizes outstanding individuals, and projects who have demonstrated discipline, vision, and passion, and the outstanding projects that service the public and make a difference in our quality of life.
Padre Dam provides water service to a population of approximately 91, 670 in the areas of Santee, sections of El Cajon, Harbison Canyon, Blossom Valley and Alpine. The District also provides wastewater services, recycled water and recreation to sections of our service area.
